Pickup TT and Pickup TTS service Truck update fix

The service pickup is now fixed and will not error upon selling it or show any warnings for triggers. It now has the Marhu warning script installed and GTX Andy’s and Rivals service script so vehicles can be customised in the field but no longer sold on the spot. Simply park the vehicle to be customised at the rear of the pickup and stand by the drivers door for the menu. It can also fill water, fuel, seeds, fertiliser, liquid fertiliser and manure. Has other options for tyres and engine power. Delete the old version from your mods folder DO NOT SELL it in game it will error.
